Default 4.5k to 5.5k boost

Hi guys,

I have a 1999 Subaru Impreza Sti v6.

It's just started doing this weird thing were between 4.5k and 5.5k it hesitates and then pulls fine again. You can hear it in the exhaust too.

Am I to assume it's from the MAF? Or could it be something else.

Thanks :-)

Give the BCS a clean see if that helps.

does it feel like you hit a brick wall when it happens or is it just a mild stumbling

The first time it was bad but then I did it again to confirm it was happening and it was just like hesitation.

I'll locate the solenoid to clean. Today it wasn't doing it at all? Driving lovely today. Possibly because the last week I've been slow town driving and then I've cleared it out or something? I don't know but I'll keep an eye on it.
